Abstract:
Background: A recent multi-center study of perinatal outcome in fetuses with Ebstein anomaly or tricuspid valve dysplasia (EA/TVD) found that 1/3rd of live-born patients (pts) died prior to hospital discharge. The purpose of this study was to explore differences in postnatal management and the relationship to outcome. Methods: This 23-center, retrospective study included 243 fetuses with EA/TVD from 2005 to 2011. Neonatal procedure (NP) was defined as surgery or interventional catheterization (cath) prior to discharge. Associations between postnatal management and outcome at discharge were explored. Results: Of 176 live-born pts, 7 received comfort care only, 11 died 〈 24 hrs of life, and 4 had insufficient data. Among 154 remaining pts, 38 (25%) did not survive to discharge. Pts who required ECMO at any point (n=18) had 83% mortality. More than half of pts (54%) did not have an NP, 34% had surgery, 8% had interventional cath, and 4% had both. The median age at 1st NP was 6 days (quartiles: 1-11). Survival did not differ between pts who had an NP and those who did not (70% vs. 80%; p=0.19) or between pts who had surgery and those who did not (68% vs. 80%; p=0.09). However, mortality differed by NP performed and whether pulmonary regurgitation, an indicator of high risk, was present prenatally (Figure). No pts with a right ventricular exclusion (RVE) died. Of 49 surviving neonates with ≥1 procedure, 28 (57%) were palliated with a shunt or RVE and 21 (43%) had a biventricular circulation. Thus, in total, 86 of 154 live-born pts (56%) survived with a biventricular circulation: 65 with medical management only and 21 with ≥1 NP. Conclusion: Among live-born pts diagnosed with EA/TVD in utero, a variety of postnatal management strategies were employed with overall poor outcomes. If surgery beyond PDA ligation is necessary, then RVE or other palliative procedure may need to be considered. A prospective, multi-center study utilizing a management algorithm would help elucidate the optimal strategy.
